Typing indicators full support for guests #9491
Description
API allows to send and receive session IDs of typing participants, and registered users are able to see who is typing (including guest names)
On the other hand, guests don't have access to conversation's participants list and as best for now is available to see that 'someone' is typing.
Works for me, but we should look into the Guests support as a follow up.
